To all'wkomit may concern:

Be it known-that I,,GUs'rAv ERNST Possn, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Printing-Inks,

' ,.doctor and evaporating of the thinner the ink will become smeary,-1 the imprint may faint or will be indistinct. This printing ink as described in this specification overof which the following is a. specification. I

This invention relates to new and useful improvements in printing inks, and more particularly to the method of compounding same.

The primary object of the present inven-.; tion is to produce a suitable printing ink,

especially adapted for printing withens" graved surfaces. v.

A further object. of the present ink,'especially adapted for printing with engraved surfaces in connection with cylinder or rotary presses.

Still another object of the present invention is to produce aisuitable vehicle for such a printing ink, allowing that the vehicle orthe ink may be thinned as needed.

A still further object of the present invention is to produce a vehicle or a printing ink where no evaporating of ethereal oils, which are inflammable and dangerous to health and property, will occur. r

Another object of the present invention is to produce a printing ink being uniform v in color which will give a clear and distinct imprint from engraved surfaces in connection with rotary or cylinder presses, and which is easily removable from the surfaces;

It has been practised to manufacture a.

printing ink for use on engraved surfaces in connection with a rotary or cylinder press, but satisfactory results have so far not been obtained. The printing inks known for this purpose are not. adaptable. 'In order to obtain a comparatively great fiuid-- vapor is in urious to health anddangerous,

, invention is to provide a thoroughly reliableprinting owingto its inflammability. In addition to those objectionable qualities, it is diflicult to remove the ink satisfactorily by thelmown mechanical means, such as what is termed a doctor of a rotary or cylinder press.

According to more or less pressure of the comes all those objections, produces an ink guaranteeing a uniformity of the color, .etc.,

retaining water and ethereal oils. The above r'eferred'do'ctor takes off easily. all surplus, ink from .the non-etched parts of the engravings used.

A mixture of the ingredients as hereafter described, will result in a homogeneous com- I v Patented J the 8, 1915. Application filed December 17, 1913. Serial No. 807,357. I

position, which will retain water and ethereal oils and by adding one or the other of the last mentioned may be thinned to a desired consistency. The mixture may then be compounded with lake colors, carbon black, mineral or anilin dyestufi's,'dry or in paste form.

The finished product Will be a printin ink having a, great fluidity and features, etc.',

1 as pointed out in the foregoing specification.

Having pointed out the purpose of this invention, I will now describe the processof manufacturing my improved printing ink.

In carrying out my invention, I use the following products, namely, casein or albumin (albumen), alkali salts and sulfonated oils or salts thereof.

The formula of they vehicle is: casein or albumin (albumen), 10; borax or its equivalent, 1.25; Turkey red oil, 20; water, 353 turpentine, 10. 1

The formula for the printing ink is: ve-

hicle, either prepared with casein or. albu-, min (albumen), 11'; anilin dyestufl. 1n pasteform or its equivalent, 5.4; carbon black, 2.2; water, 8.8; turpentine, 2.

It is of course understood that I do not limit myself as. to the respective amount of'.

each ingredient stated, this is merely the preferred composition of thedifferent mate rials; but I may change the quantity withwith lake colors, carbon black, inineral dye out departing from the scope of my inven stufis and ethereal oils and water used in tion. substantially the proportions described.
